  Hello Fiona,

  Thank you for your response.

  You are facing this problem might because of Java program on your computer.

  I suggest you perform the clean boot and check the status of the issue, which will help you identify the problem.

  Keep the computer in a clean boot and check the status of the issue. If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem. Continue with the remaining steps to pin-point on the third party service. After find you the program that is causing the problem, you will have to perhaps to update or install a newer version of the program, if you rarely use that you should consider uninstalling the software.

• Access map SD BlackBerry main class

  Hello, please I have a problem with access to the sd card in my main class, basically I can access the sd card but not my main class, a screen should be displayed with a touch for me to the screen with access to the database, please can someone explain why this is so?

  If you have solved it another way you can mark this as resolved then?

  Coded correctly, there should be no problem access the SD card before a screen.

  If you don't want to try to move the code in a start-up treatment that is started after your Application is created, then it's OK.  But if you want us to help to do that, then I suggest you rework your hand so that the access to the SD card does not start until your Application has been created and entered into the distribution.

  Reference to article that I made, the key role which is:

  invokeLater (new Runnable() {}
  public void run() {}
  doStartupWork();
  }
  });

  You put the code to make the SD card access in the present and you will put your push button to your screen in this too.

  But if you are happy with what you currently have, please that mark it as resolved.

• "Could not find the main class" Java error on Windows 7, but not Windows XP

  Hi all

  It's the first app I try to package and virtualize with ThinApp.

  It is an old business application that usually runs on Windows XP SP3 x 86.

  The. MSI that I generated with Thinapp works very well when it is installed on a Windows XP SP3 x 86.

  However, our main goal to use Thinapp is to install on a Windows 7 SP1 x 64.

  But in doing so, the application triggers a Java Virtual Machine Launcher error message saying: "could not find the main class. Program will exit. »

  I thought that it was because the app includes a 1.4.2 JVM and that my XP has not any JVM pre-installed, but the main image on my W7 has a 1.7 JVM. But even after I uninstalled the 1.7 and installed JVM 1.4.2 on the W7 machine, I kept getting the error message so I guess that it is not bound.

  Y at - it an option that I missed during my MSI generation so that it can run on a Windows 7 x 64?

  Thank you all for your help.

  D.

  With the help of Lachi, we found that the app natively works on W7, no need for ThinApp it if the goal is just to make it work on W7, from a XP world.

  The only change we had to make (and the error was the same ThinApp-ed, which is what I originally shared) is that the application should work with Windows 7 in "classic" mode "of the screen (without Aero and the menu start XP-style). This is because the application runs an old integrated version of Java (1.4) and it makes the system calls seeking specific .dll to display, which are not accessible by default if Aero is enabled.

• The main class and the class structure of game

  Hello.

  I m doing a game and now I wonder if it s handy to have a class named hand for my game.

  I thought I'd have a Preloader, Console and play classes.

  Now I Don t know.

  Maybe better to have a main class that loads including a preloader that loads the Console that it s loads of game.

  That s the best way to make an application of game? I m talking best practices.

  And why if so there must be a main class that extends Sprite?

  Thank you

  What is in a name?  It calls for what you want.

  for the best practices in the design of the class, google: models of object-oriented design.   It is a mature topic with lots of available information.

  and your document class must extend sprite or movieclip classes because your fla document has a timeline (with one or more images).

• Define the main class in the project

  Hi, I have a project in Eclipse with several main methods as I test different things. My question is: How can I change the main method of the project? Because Eclipse is still running the same major and I want to run the code using different network. Thank you

  Greetings.

  For the record, make sure you have only one main method that serve as the entry point for the application.

  But like you said that your goal is now to make a quick test, do a right-click on the class that contains the entry point (main method) you want to test, click on run as-> Blackberry Simulator.

  Make sure that the class you are testing extends the request or UiApplication in order to run it. Otherwise, this entry point will be useless at all.

  In case you want to define an entry point for the project, just delete all the alternative entry points (main methods).

  Good luck. I hope this helps.

• access the property of the main class in loaded swf.

  Hello

  I have a main.fla, its document class is main.as. the code in main.as is

  package

  {

  import flash.display.MovieClip;

  SerializableAttribute public class Main extends MovieClip

  {

  private var loading: loading;

  public var trovami:Number = 10;

  public void Main()

  {

  stage.frameRate = 31;

  loadSWF();

  }

  private function loadSWF (): void

  {

  loading = new Loading (this);

  }

  }

  }

  LOADIND. ACE is another class where I load another swf name is my_swf.

  class loading code is:

  package

  {

  import flash.display.MovieClip;

  to import flash.display.SimpleButton;

  import flash.text.TextField;

  import flash.display.Loader;

  import flash.events. *;

  import flash.net.URLRequest;

  SerializableAttribute public class loading extends MovieClip

  {

  private var _fla:MovieClip;

  private var url: String;

  public var val: String;

  private var loader: Loader;

  public void Loading(fla:MovieClip)

  {

  _fla = fla.

  init();

  }

  private function init (): void

  {

  URL = 'my_swf.swf';

  var request: URLRequest = new URLRequest (url);

  loader = new Loader();

  initListeners (loader.contentLoaderInfo);

  Loader.Load (request);

  }

  private void initListeners(dispatcher:IEventDispatcher):void

  {

  dispatcher.addEventListener (Event.COMPLETE, complete);

  }

  private void completato(event:Event):void

  {

  _fla. AddChild (Loader);

  Loader.y = 10;

  Val = "Hello".

  }

  }

  }

  and the class of the loaded swf document is Main2. in my_swf.fla, there is a text, that his name is:

  a_txt.

  I so use class in Main2 for loading text property.

  Code of Main.as is

  package

  {

  import flash.display.MovieClip;

  import flash.text. *;

  Main2/public class extends MovieClip

  {

  public void Main2()

  {

  a_txt.text = val;

  }

  }

  }

  where val is the property of class loading.

  so, how do I access.

  You have a reference to your movie loaded into your class loader - instead of simply set val to string - add a method in your class Main2 - and call it loading - passing the string which him. Push not pull...

  Hand 2 becomes:

  public void Main2() {}
  a_txt. Text = Val;

  }

  public void setText(val:String):void {}
  a_txt. Text = val;

  }

  And then in your class loader - when you have finished loading only call setText:

  private void completato(e:Event):void

  {
  addChild (loader);
  Loader.y = 10;
  MovieClip (loader.content) .setText ("hello");
  Val = "Hello";
  }

• fieldChange get variables from the main class

  I'm doing a simple calculator that users enter numbers, press on calculate, and the answer is displayed in the status bar.  The problem I have is that when I try to get the EditFields values in the fieldListener, I get an error that says that the variable was not found.  Here is an example of the code that I have:

          }
  
          total = sellVal * taxrateVal + sellVal    
  
              LabelField newpmt = new LabelField("Total: " + total, LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH) {

• How to access the instance property of the main class via child class

  Hi I hv done 3 classes objecthandler, box and nav

  NAV is child chass objecthandler, I hv make an instance of objecthandler box and now I want to access the property of box via NAV... See the code

  Class Objecthandler

  package code {}
  import flash.display.MovieClip
  import code.box
  import code.nav
  
  public class objectHandler extends MovieClip {}
  public var container: box
  public var navigation: nav

  public void addObjects() {}
  
  Navigation = new nav()
  addChild (navigation)
  navigation.addEvents)
  navigation.x = 275
  navigation.y = 400
  
  container = new box()
  addChild (container)
  putcontainer ("default")< < works well here
  }
  public void putcontainer(page:String) {}
  Container.OpenPage (page) < < when this function is executed it returns ("page is open"+ page)
  }
  }
  }

  Class of NAV

  package code {}
  import flash.display.MovieClip
  import flash.events.MouseEvent
  import flash.display.DisplayObjectContainer
  import code.box
  
  public class nav extends objectHandler {}
  public void nav() {}
  
  }
  
  public void addEvents() {}
  homeBtn.addEventListener (MouseEvent.CLICK, releaseFun)
  galleryBtn.addEventListener (MouseEvent.CLICK, releaseFun)
  productsBtn.addEventListener (MouseEvent.CLICK, releaseFun)
  contactBtn.addEventListener (MouseEvent.CLICK, releaseFun)
  }
  
  public void releaseFun(event:MouseEvent):void {}
  putcontainer(Event.currentTarget.Name) < < showing the error over here
  }
  }
  }

  You should review your logic.

  It is not supposed have nav extend objectHandler and then has an objectHandler method that creates a new instance of nav.
